Preheat your oven to 425°F (220°C).
Prepare the chicken by rinsing it under cold water and patting it dry with paper towels.
Season the cavity of the chicken with salt and pepper, then place half a lemon inside.
In a bowl, combine olive oil, garlic, rosemary, thyme, salt, and pepper.
Rub the herb mixture all over the chicken, making sure to get under the skin where possible.
Tie the legs together with kitchen twine and tuck the wing tips underneath the chicken.
Place the chicken in a roasting pan. Optionally, add chopped vegetables around the chicken.
Roast in the preheated oven for about 1 hour and 15 minutes or until the internal temperature reaches 165°F (75°C).
Let the chicken rest for at least 15 minutes before carving.
Carve the chicken and serve with the roasting vegetables.
